For your AI agents
Give your agents every tool, without giving them the keys
One MCP Gateway connects Claude, Cursor, or your own agents to the enterprise tools your customers already run, with per-tenant auth, scoped permissions, and an audit trail. Your agent acts on Salesforce or Slack for one customer without ever seeing another customer's data.
What the MCP Gateway gives your agents
Point any MCP client at fastn and your agent discovers CRM, ticketing, finance, and HR tools as callable actions, no per-tool integration code.
Every call runs under one customer's credentials with scoped permissions. Blast radius stays contained, and every action is auditable.
Auth flows, token refresh, rate limits, and vendor API changes are handled by fastn. You run agents; fastn runs the plumbing.
Built for how agents are deployed
Your AI SDR, support agent, or ops copilot acts inside each customer's stack, isolated per tenant.
Claude or Cursor connected to your company's tools through one governed gateway instead of a pile of API keys.
Embed agent-powered features that use each customer's connected tools, the same embed, agent-ready.
Connect your first agent in minutes.
